OnsenUi Angular and Login

I am trying to develop a mobile app with onsen + cordova

What I need:

Load the login.html page when launching the application. If the app detects that the user is logged in, it is redirected to home.html

For each "secure page" I want to call the function that was found during user registration. If I don't want to redirect the login page.

All "protected pages" have a slide menu.

After what I did:

index.html

<html ng-app="app2gest">
    <head>
        <meta charset="utf-8">
        <meta name="apple-mobile-web-app-capable" content="yes">
        <meta name="mobile-web-app-capable" content="yes">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height"/>

            var newArr = [];
            for (var i = 0; i < arr.length; i += size) {
                newArr.push(arr.slice(i, i + size));
            }
            var cachedParts;
            var arrString = JSON.stringify(arr);
            cachedParts = arrayCache.get(arrString + size);
            if (JSON.stringify(cachedParts) === JSON.stringify(newArr)) {
                return cachedParts;
            }
            arrayCache.put(arrString + size, newArr);
            return newArr;
        };
        return filter;
    });


})();

      

For the dummy imNotInLoginPage () function at the start of the app, if appNavigator.getCurrentPage () is running, but appNavigator.getCurrentPage (). page is empty

After login, if I call appNavigator.getCurrentPage () it is undefined and I get js undefined error.

How can I check if I am on a login page or a different one?

And a very big question, is this a good estimate in angular?

Otherwise, how can I achieve this goal with angular + onsen ???

Onsen theme support is very poor. I found other solutions using angular route, but they are not onsen compatible.

I am going crazy to implement this standard thing. I hope someone can help me by providing complete example code.

thank

I created a sample. If I misunderstand what you mean, please tell me.

index.html

 <!DOCTYPE HTML>
<html ng-app="myApp">
<head>
    <script src="components/loader.js"></script>
    <link rel="stylesheet" href="components/loader.css">
    <link rel="stylesheet" href="css/style.css">
    <script src="js/app.js"></script>    
</head>
<body>
    <ons-navigator var="myNavigator" page="login.html">
    </ons-navigator> 
</body>
</html>

      

app.js

var myApp = angular.module("myApp", ['onsen']);

myApp.controller('loginCtrl', function($scope) {

    if(checkLogin()) {
        openProtectedPage();
    }

    function openProtectedPage() {
        alert("you are already logged in. open protected page");
        setTimeout(function() {
            myNavigator.pushPage('protected.html');    
        }, 1000);

    }

    function checkLogin() {
        //temporariry return true;
        // please write your own logic to detect user login;
        return true;
    }    
});

      



login.html

<ons-page ng-controller="loginCtrl">
    <ons-toolbar>
        <div class="center">Login Page</div>
    </ons-toolbar>

    <div style="text-align: center; margin-top: 30px;">
        Email: <input type="text" />
    </div>

    <div style="text-align: center; margin-top: 30px;">
        Password: <input type="text" />
    </div>  

    <div style="text-align: center;margin-top: 30px;">
        <ons-button>
            Sign In 
        </ons-button>
    </div>
</ons-page>

      

protected.html

<ons-page>
    <ons-sliding-menu var="app.slidingMenu" menu-page="menu.html" main-page="page1.html" side="left" type="overlay" max-slide-distance="200px">
    </ons-sliding-menu>
</ons-page>

      

I hope this example helps you.
